Crate wayle_brightness 

Backlight control for internal displays.

All state is exposed via Property fields that update automatically when brightness changes.

Quick Start

use wayle_brightness::{BrightnessService, Percentage};

let Some(brightness) = BrightnessService::new().await? else {
    return Ok(());
};

if let Some(device) = brightness.primary.get() {
    println!("{}: {}", device.name, device.percentage());
    device.set_percentage(Percentage::new(50.0)).await?;
}

Watching for Changes

use wayle_brightness::BrightnessService;
use futures::StreamExt;

let mut stream = brightness.primary.watch();

while let Some(maybe_device) = stream.next().await {
    if let Some(device) = maybe_device {
        println!("brightness: {}", device.percentage());
    }
}
